Gimkit assignments let students practice quiz content on their own time, without a teacher-hosted live session. Teachers set a game mode, a completion goal, and a due date — students play from any device and results appear automatically. This guide covers everything from setup to reading reports. What Are Gimkit Assignments? Gimkit assignments are self-paced sessions tied to a specific kit and game mode. A teacher creates the assignment, sets a cash or question goal, and shares a link. Stu...

When I was a student in grade school biology, before I had an inkling of my destiny to become a clam man, I remember learning about food webs. We learned that one part of the food web was made up of autotrophs (“self feeders”), such as plants and algae, which make their own food via photosynthesis (note that there are autotrophic organisms also using chemosynthesis to make food, but we’ll leave those for another blog). The other main portion of the food web are the heterotrophs (“diffe...

I was a speaker last month at the Pragmatic Summit in San Francisco, where I participated in a fireside chat session about Agentic Engineering hosted by Eric Lui from Statsig. The video is available on YouTube . Here are my highlights from the conversation. Stages of AI adoption We started by talking about the different phases a software developer goes through in adopting AI coding tools. 02:45 I feel like there are different stages of AI adoption as a programmer. You star...

Recently I came into posession of a few Apple Xserves. The one in question today is an Xserve G5, RackMac3,1 , which was built when Apple at the top—and bottom—of it's PowerPC era. This isn't the first Xserve—that honor belongs to the G4 1 . And it wasn't the last—there were a few generations of Intel Xeon-powered RackMacs that followed. But in my opinion, it was the most interesting. Unfortunately, being manufactured in 2004, this Mac's Delta power supply suffers from the Cap...

I think back to how I used to think about how my finger tips would hurt if I learned to play the guitar. I was right: my fingers do get a bit sore. But with practice playing for longer gets easier. I am so glad I started to play. I have been continuing to learn new Taylor Swift songs lately, singing along where I can. Because I have only been playing for a few months, every song has something challenging to practice: singing with the strumming pattern that fits with the song, moving between two ...

No matter where you look, a bell curve is close by. Place a measuring cup in your backyard every time it rains and note the height of the water when it stops: Your data will conform to a bell curve. Record 100 people’s guesses at the number of jelly beans in a jar, and they’ll follow a bell curve. Measure enough women’s heights, men’s weights, SAT scores, marathon times — you’ll always get the… Source No matter where you look, a bell curve is close by. Place a measuring cup in y...

Today in r/golang , user Leading-West-4881 asked: Is a repository layer over sqlc over-engineering or necessary for scale? I’m building a notification engine in Go using sqlc for the DB layer. Do you just inject *db.Queries into your services, or do you find the abstraction of a repository layer worth the extra code? I attempted to answer it there and the gist is correct. But I wrote it in a hurry so the example and the explanation could be better. Capturing it properly here. ...

I love Monobook . It was the skin Wikipedia when I started contributing back in 2004, and it’s still the skin I have enabled in my Wikimedia account. It’s also the one Clara and I use on the Sasara Wiki , our family wiki. The volunteer maintainers have done an amazing job keeping it current, but I also add a few more tweaks to MediaWiki:Monobook.css . This sets the base font a bit larger; the absolute size is defined elsewhere, so this gets pretty close to 1em for the main body text. ...

All my clients wanted a carousel, now it's an AI chatbot! 2026-03-14 12:55 It always starts the same way. The client pulls out their phone mid-meeting, navigates to a competitor's website, and holds the screen up like evidence. "You see? They have one of those." A little bubble. Bottom right corner. Blinking... For years, that gesture was about carousels. Every homepage had to have one, big, slow, full of stock photos that nobody asked for. I built dozens of them. They spun. They faded. ...

I started work on Distributed Systems Design by Example exactly 212 days ago. The first draft is now done, and I’ve learned a lot while writing it, just as I learned a lot by writing books on software design in JavaScript and Python . However, I don’t know if I will ever finish this book: people don’t seem to read long-form technical writing any longer, and there several pieces of fiction that I want to get over the finish line. Still, I hope what’s there is useful. I started work ...

It’s a common position among software engineers that big egos have no place in tech 1 . This is understandable - we’ve all worked with some insufferably overconfident engineers who needed their egos checked - but I don’t think it’s correct. In fact, I don’t know if it’s possible to survive as a software engineer in a large tech company without some kind of big ego. However, it’s more complicated than “big egos make good engineers”. The most effective engineers I’ve worked...

“I know we are going to take a very long road, into darkness; but I know I can't turn back.” ― The Lord of the Rings Black Abyss Waitomo is mostly known for their glowworm caves. Most people book a short boat ride to view the countless New Zealand glowworms ( Arachnocampa luminosa ). I probably wouldn't include this activity in my trip if there wasn't a much more adventurous alternative: the Black Abyss , a caving tour. After putting on a wetsuit, you start with a 35 m a...

I've liked Cryptic Crosswords...somewhat. In the past. They're a bit tricky for me and I haven't really put in the time to be comfortable enough to have fun solving them. Anyway, the Wordle guy has a new website where he aims to teach people how to solve Cryptics. If you're not familiar, Cryptic Crosswords follow a very particular format for their clues. Let's take one of the Parseword examples: Cooked rustic orange (6). The (6) refers to the number of letters in the result. So we...

Back in 2024 I went through the process of losing weight, and was fairly successful . I went from ~111kg (244lbs) to ~103kg (226lbs). My target was 100kg (220lbs), so I got very close. But then, in August 2024, I was promoted in work, ended up working way more hours, and my health suffered. I ended up burned out and ultimately I stepped down a few months ago. Which was honestly the right thing to do . Anyway, for the year or so that I was in that role, my weight slowly crept back up ...

I tend to focus on the origin of the computer within the military. Particularly in the early days of digital computing, the military was a key customer, and fundamental concepts of modern computing arose in universities and laboratories serving military contracts. Of course, the war would not last forever, and computing had applications in so many other fields—fields that, nonetheless, started out as beneficiaries of military largesse. Consider education. The Second World War had a profound ...

I wanted to explore the extent to which Claude Code could build a data pipeline using dbt without iterative prompting. What difference did skills, models, and the prompt itself make? I’ve written in a separate post about what I found ( yes it’s good; no it’s not going to replace data engineers, yet ). In this post I’m going to show how I ran these tests (with Claude) and analysed the results (using Claude), including a pretty dashboard (created by Claude): I wanted to ...
